Goal is green. Trap is red. Obstacles are dark. Visit counts appear inside cells. Change policy settings and compare trajectories.

Policy formula reference

π(a|s) = P(A_t=a | S_t=s)

G_t = R_t+1 + γR_t+2 + γ²R_t+3 + …

A(s,a) = Q(s,a) − V(s)

δ = R + γV(S′) − V(S)

ρ = π(a|s) / b(a|s)

H(π) = −Σ_a π(a|s) ln π(a|s)

Frequently asked questions

It covers policy fundamentals, evaluation, improvement, gradients, safety, deployment, and practical debugging.

How many questions are included?

The bank contains 132 questions across beginner, intermediate, advanced, and expert levels.

Can I focus on one topic?

Yes. Select one or more categories before starting your attempt.

Does the quiz support calculations?

Yes. Numerical questions cover returns, epsilon-greedy probabilities, TD updates, advantage, entropy, and importance sampling.

What does adaptive mode do?

It reorders remaining questions toward easier or harder levels based on recent accuracy.

Are results saved?

Current attempts and summary history are stored in browser local storage.

Can I export my report?

Yes. Use the copy, CSV, PDF, or print controls after finishing.

What is the simulator for?

It demonstrates deterministic, random, epsilon-greedy, and safer policies in a configurable grid world.

Does the page require a database?

No. The quiz runs as one PHP file and stores progress in the browser.
